Please select the correct input voltage before use. We recommend using a transformer with a rated power of 1.5 to 2 times the load power .2. The equipment will generate heat during use. Please pay attention to heat dissipation and ventilation during use, and keep away from high temperature, humidity, inflammable and explosives.3. The power transformer should be placed in a dry and well-ventilated area at all times. Do not block the side cooling holes with foreign objects to affect heat dissipation.4. To ensure safety, please power on the transformer for 15 minutes before connecting it to your appliance for use. 5. For capacitive load, just leave enough allowance on the rated power capacity of the unit to avoid overloading.6. Before turning on the power transformer, please carefully read the English manual and ensure that the electrical power has been turned off. At the same time, check the rated power consumption of the equipment to avoid overloading the equipment. Please cut off the power supply after use. 7. Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement, and make sure you do not mind before you order.
